Sodium carbonate revisited
Abstract
A single-crystal X-ray structure analysis is presented for the incommensurate room-temperature phase γ and for the commensurate phase δ at 110 K of anhydrous sodium carbonate. A previous study of phase δ included only first-order satellites; this study included higher-order satellites. Both phases are compared within the unified superspace group approach.
